• Casting/Forging: Critical load-bearing components, such as caster brackets and connecting plates, may undergo forging or specialized casting processes to enhance metallurgical properties, eliminate internal defects, and provide superior fatigue resistance.
• Cutting: CNC laser or plasma cutting machines are used to precisely cut steel plates and profiles, ensuring exact dimensions and minimizing material waste.

2. Fabrication and Welding:

• Precision Welding: Skilled, certified welders employ techniques like Gas Metal Arc Welding (GMAW) or Submerged Arc Welding (SAW) to join structural components. Adherence to international welding standards (e.g., AWS D1.1, ISO 3834) is strictly maintained.
• Non-Destructive Testing (NDT): Weld integrity is verified through methods such as ultrasonic testing (UT), magnetic particle inspection (MPI), and visual inspection (VI) to detect any internal or surface flaws, ensuring the structural soundness of the 4000 lb gantry crane.
• CNC Machining: Components requiring high dimensional accuracy, such as axle mounts for casters or pin holes for adjustable sections, are finished using CNC machining centers. This guarantees smooth operation and precise alignment.

3. Surface Treatment and Finishing:

• Pre-treatment: All steel surfaces undergo thorough cleaning, degreasing, and shot blasting (SA 2.5 grade) to create an optimal profile for coating adhesion, significantly enhancing corrosion resistance.
• Industrial Coating: A multi-layer industrial-grade powder coating or epoxy paint system is applied. This finish provides superior protection against abrasion, chemicals, and environmental factors, extending the service life of the adjustable gantry crane, especially in corrosive environments often found in petrochemical or water treatment industries.

4. Assembly and Testing:

• Modular Assembly: The crane is assembled with precision, ensuring all adjustable components function smoothly and securely.
• Load Testing: Each 4000 lb gantry crane undergoes static and dynamic load testing, typically at 125% and 110% of its rated capacity, respectively, in accordance with ASME B30.17 and EN 15011 standards. This verifies structural integrity and hoist performance.
• Deflection Testing: The main beam's deflection under full load is measured to ensure it remains within specified limits, preventing premature fatigue and ensuring safety.
• Compliance: Products are certified to meet international standards such as ISO 9001 for quality management and CE marking for European market conformity, signifying adherence to strict safety and performance criteria.

This rigorous process guarantees a service life often exceeding 20 years with proper maintenance, ensuring a significant return on investment for industrial clients.
